Metastatic Urothelial Carcinoma of the Prepuce and Glans Penis: Suspected Implantation of Non-Muscle-Invasive Bladder Cancer via Urine

Abstract

Cutaneous metastatic implantation of non-muscle-invasive urothelial carcinoma via urine is a rare finding, and only few cases have been reported in the literature. Here, we present a case of metastatic urothelial carcinoma of the prepuce and glans penis, which was suspected to be an implantation of non-muscle-invasive bladder cancer via urine. The patient had pseudophimosis of the penis, and contact with urine containing urothelial carcinoma cells was considered to be the cause of the metastatic implantation.
